A DEVICE FOR WELL INTERVENTION

摘要

A device (3) for well intervention by means of a coiled tubing (40) and a wireline (41). The device comprises a cantilever (12) adapted to be arranged on a vessel (1) that is configured to be brought to a petroleum well (16) at sea. The device further comprises a displacement arrangement (35), a first feeding device (38a) for feeding the coiled tubing (40) and a second feeding device (38b) for feeding the wireline (41). The first feeding device and the second feeding device are arranged in engagement With said displacement arrangement. The displacement arrangement is adapted to displace the first feeding device and the second feeding device horizontally in relation to the cantilever so that one of the first feeding device and the second feeding device is positioned at the petroleum well for enabling well intervention by the coiled tubing or the wireline.
